This invention relates to an attachment for a conventional disk type cultivator, particularly of the two disk type, in the form of an attachment which is readily installable and easily removable, which will effectively clean the disk of the cultivator and prevent their clogging with mud and the like, so as to enable the cultivating of a field much sooner than is usually possible after arain or damp pGIOd. y ,Y Y.

lt is an object of this invention to provide a device of the character described above which is composed of few and simple and rugged parts and which is not only elicient in action, but which is durable and does not require frequent replacement. g

lt is also an object of this invention to provide a device of the character described which can be cheaply and easily manufactured, which is adjustable, and which may be made in right and left hand forms according to requirements.

These and other objects of the invention, its nature, and its composition and arrangement and combination of parts will be readily understood by anyone acquainted with the art to which this invention relates upon consulting the following description of the drawings. y

In the drawings: l

Figure 1 is a general perspective group view of the device of the invention installed in connection with a conventional disk cultivator. f l

Figure 2 is a top plan view thereof.

Figure 3 is an elevational view of the scraper blade.

Figure 4 is a perspective view of the adjustable cross bar. Y

Figure 5 is a view of the blade holding bracket.

Figure 6 is a perspective view of the V- shaped bracket supporting the blade structure on the cross bar.

Figure 7 is a view of one of the bolt locks, and

Figure 8 is a view of another of the bolt locks.

The numeral 5 refers generally to a cultivator disk supported on the usual shaft 6 by 1931. serial No. 547,122. y

the 'vertical shank"7` mountedfin the usual casting generally designated 8, and the numeral 9 refers generally to the scraper attachment of the invention.

The `device `of the invention comprises a clamp 'composed of the block 10 of generally circular form and provided onone face with the' radially arranged grooves 11 to provide' a gripping surface, and onv the other face with the depression 12 ofthe same radius of 4curvature as the eye through the block 10.v The eye 13 is passed. about the vertical shank 7 4and the `bolt 145 is passed through one of a series of holes 15 in the horizontal cross bar generallyidesignated 16, and nut 17 is to be dra-Wn against the horizontal cross memberl so as to `clamp the upright shank 7 in the eye 13 'andA against lyfclamps the cross bar 1 6 in the desired adj usted position. At one end of the cross bar 16 and onthe forward face thereof is bolted a V-shaped bracket generally designated 18, whoseV aperture is less 'than ninety' degrees. The V-shaped bracket is providedwith bolt holes 19 and`20 to receive bolts, whose nuts are adapted to be -lockedby the V-shaped lock generally designated 21 which has the deflected end portions 22 for engaging one 'side of the nuts,'the lock adapted to be placed inside of the V-shaped bracket 18 as seen in Figure1.

VUpon the upper surface of the horizontal plate of the bracket 18v is supported an L- shaped blade holder 23 which has the bolt holes 211 in the bottom portion 'and 25 in the upright'portion. Bolts 26 are passedthrough the holesr 25 and 25a in the upright portion of the blade holding bracket Vaffording angular adjustment of the blade and they are adapted to be locked by a locking strip 27 after they pass through a plurality of holes 28 in a generally rectangular scraper blade 29, so as to support the blade in vertical position in engagement with the disk 5. rlhe scraper blade 29 is vertically elongated and is provided with a curvate edge, and may be otherwise deformed to properly engage the contour of the disk 5.

The above is thought to be a description 134 of an eye bolt 114 passed i the block 10. This clamping action also solid'- suiliciently in detail to enable anyone acquainted With the art to Which this invention relates to make, construct and use the same,

and it is therefore thought that further de- 5 scription is unnecessary.

Inasmuch as various changes and modifications might be made in the device of the invention to make it to suit different types and makes of the disk machines, it is to be delinitely understood that I do not desire to limit the application of this invention to the particular modifications set out herein to illustrate the principles thereof, and any change or changes may be made Within the spirit and scope of the invention.

Having thus described my invention, what I claim as new is:

1. A disk scraper attachment for cultivators and the like comprising'a clamp adapted to be attached to the vertical shank of one of the disk supports of the cultivator or the like, a longitudinally adjustable cross bar also held by the clamp, an adjustable angle bracket on the cross bar, an adjustable blade bracket on the angle bracket, and a vertically adjustable scraper blade on the blade bracket.

2. A disk scraper attachment for cultivators and the like comprising a clamp adapted to be attached to the vertical shank of one of 3o the disk supports of the cultivator or the like, a longitudinally adjustable cross bar also held by the clamp, an adjustable angle bracket on the cross bar, an adjustable blade bracket on the angle bracket, and a vertically adjustable scraper blade on the blade bracket, said clamp being capable of being vertically adjusted on said shank.

3. A disk scraper attachment for cultivators and the like comprising a clamp adapted to be attached to the vertical shank of one of the disk supports of the cultivator or the like, a longitudinally adjustable cross bar also held by the clamp, an adjustable angle bracket on the cross bar, an adjustable blade bracket on the angle bracket, and a vertically adjustable scraper blade on the blade bracket, said clamp being capable of being vertically adj usted on said shank, and said cross bar, angle bracket and blade bracket cooperating to permit angular positioning of the scraper in any direction.

In testimony whereof I aiiX my signature.
